The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://cctraff.ru/strik?utm_term=black+baby+names+that+start+with+d'. ClamAV also detected it as 'Pdf.Phishing.Trojan-d2528dad23a95d95-d2528dad23a95d95-10044376-0'. The ML classifier strongly flagged this PDF as malicious. The document body appears to be obfuscated or corrupted, but the presence of a malicious URL is sufficient evidence of a phishing or malware distribution attempt.

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.

Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://cctraff.ru/strik?utm_term=black+baby+names+that+start+with+d In PDF document text
